Convert WebP to PNG

Load a WebP image and this page re-encodes its decoded pixels as a PNG, entirely in your browser with no upload. Transparency comes through intact and there is no quality setting to tune. Keep one caveat in mind: PNG stores those pixels exactly, so detail a lossy WebP already discarded stays gone, and the PNG is usually the bigger file.

Tool facts

WebP input limit
12 MiB per file, up to 8,192 px per side and 24 MP
Output encoding
Lossless PNG; the Quality slider is hidden for this target
Transparency
The full alpha channel is written into the PNG
Batch
Up to 12 files and 96 MiB in; combined PNG output is capped at 100 MiB
Metadata and color
EXIF and ICC data in the WebP are not copied; pixels pass through an sRGB canvas
Dimensions
Width and height stay identical to the source

How to save a WebP image as PNG

  1. 01

    Add the WebP files

    Use Choose file or drop images onto the drop zone. Detected input names the format read from the file's own signature, not from its extension.

  2. 02

    Confirm the target

    Convert to already shows “PNG — lossless, keeps transparency”, so there is no quality or background control to set.

  3. 03

    Convert

    Press Convert image. The result panel lists Input, Output, Dimensions and Size change for the file you just converted.

  4. 04

    Save the PNG

    Download stores the file as toolars-<name>.png. When several WebP files were queued, Download all (zip) collects them in one archive.

When a WebP has to become a PNG

A WebP file needs a PNG copy when an editor, office document or ingestion pipeline accepts only PNG or JPEG. PNG is the target that changes nothing visible and keeps the alpha channel.

What PNG cannot do is undo compression. If the WebP was saved lossily, its block artifacts and smoothed gradients are written into the PNG exactly as decoded. The gain is that later edits and re-saves of the PNG add no new loss on top.

Plan for a larger file: PNG stores every decoded pixel losslessly, and how much it grows depends on the image. The Size change readout reports the measured difference for each file.

Common questions

Does converting WebP to PNG improve image quality?
No. The PNG holds the pixels the browser decoded from the WebP, artifacts included. It prevents further loss when you edit and save again, but it cannot bring back detail the WebP encoder removed.
Why is the PNG several times larger than the WebP?
Lossy WebP throws away detail to save bytes; PNG keeps every decoded pixel and only compresses them losslessly, so the same picture can take several times the space. Check the Size change readout for the actual figure.
What happens to an animated WebP?
The PNG this page writes is always a single still image, so the animation does not carry over. If you need one particular frame, export that frame from the source app first.
Are soft shadows and anti-aliased edges kept?
Yes. PNG stores a full alpha value per pixel, so semi-transparent shadows and smooth edges from the WebP keep their partial transparency instead of being cut to fully on or off.
Can I convert a whole folder of WebP files?
Select up to 12 files with a combined input of 96 MiB and they convert one after another into a single ZIP. Because PNG output grows, a batch whose results would exceed 100 MiB is stopped; split it into smaller groups.
